Hello, 

I have been using my Archer C6 for Wifi (both 2.4 GHz and 5 GHz) and TV through LAN. All was working fine with an exception of TV showing that LAN is turned on/turned off constantly. Today I tried to plug LAN to PC. PC shows that Ethernet is identifying, then it shows that there is no Ethernet, and so on. Router itself also restarts and light which indicates internet through LAN turn on/off constantly. Now router's LAN cabel is plugged to turned off PC and interesting thing that all 5 lights on router flashes, router works fine. But if I will turn on PC, it will start to reboot, and PC will not show good Ethernet connection. Where it might be a problem?

Thanks!
